Where do I enter my daily sales

Good day, @deedie62-yahoo-c.

I'd be glad to assist you in recording your sales transactions in QuickBooks Online (QBO).

We can use the Sales Receipt to enter your daily sales in QBO. You can create a single receipt for the entire day sales. This can save you few clicks. Here's a video on how to record a sales receipt. 

You may also want to track them in one customer account. To do so, create one customer name for these sales. Here are the steps: 

1. Select Sales from the left panel, choose Customers.
2. Click New customer then add necessary details in the Customer Information page.  You can name it as Daily Sales. 
   
   
3. Then hit Save. 

I'll leave this link about recording daily sales. This has additional details in adding your total daily transactions in QBO.
You can run and customize report to review your revenue. Read through this article about customizing report this can gets you steps on saving any sales report you prefer to view with specific filters. 

Let me know if you have other concerns in managing your sales in QBO. I'm always here to help. Have a good one.
